Permanent Tightness Prevents Risk of Explosion
One of the most potential dangers associated with the use of hydrogen is its extremely high flammability. With four to 75 percent by volume in air, its explosion range is significantly wider than other gaseous energy sources such as propane or butane. This greatly increases the risk of explosions.
This risk is minimized using sliding gate valves as there are various designs on the market. According to the Technical Rules for Hazardous Substances( TRGS), Schubert & Salzer’ s sliding gate valves are permanently leak-tight and meet the requirements of the Technical Instructions on Air Quality Controls 2021( TA-Luft 2021)
In its production, processing, and transport, hydrogen places the highest demands on plant and system components.
in accordance with EN ISO 15848- 1. Special versions are available to achieve body leakage rates of less than 5 x 10-⁶ mbar l / s and are therefore suitable, even for use in closed rooms.
" In hydrogen applications – whether in production, storage or transport – every component must work absolutely reliably even under demanding conditions," says Christoph Lukasik, Head of Design and Development at Schubert & Salzer.
In addition to the performance of sliding gate valves made from high-grade austenitic steels, they serve as a critical component that is capable of delivering reliable flow control, enhanced safety, and long term operational efficiency in the hydrogen industry. •
